hibernate在tomcat下无法连接mysql数据库 30C

hibernate在eclipse下能连接mysql数据库,但是发布到tomcat下就显示:
1.No suitable driver found for jdbc:mysql:///hibernate,
2.Error calling DriverManager#getConnection,
3. Unable to create requested service [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment],这三个异常。
我用的是apache-tomcat-7.0.52,驱动包mysql-connector-java-5.1.7-bin.jar。
测试过同一段代码在eclipse下用hibernate和dbutils都能连接数据库,这样说明代码和jar包应该都是没问题的,一发布到tomcat下就只有dbutils方式才能访问到数据库。应该就在hibernate发布到tomcat这一过程出了问题

另一种情况就是把驱动包换成mysql-connector-java-5.0.4-bin.jar,不管是eclipse下还是tomcat下,hibernate和dbutils方式都会抛上述异常,5.0.4这个包是以前用dbutils方式连接数据库的项目用的,之前毫无问题。是不是hibernate还和驱动包版本有关?
 昨天刚学的hibernate,今天遇到这状况查了一天都没发现问题在哪,上来问问大神们。。。

hibernate在tomcat下无法访问数据库
hibernate在tomcat下无法访问数据库 hibernate在eclipse下可以连接到数据库,一发布到tomcat就报错: 1.No suitable driver found for jdbc:mysql:///hibernate; 2.Error calling DriverManager#getConnection; 3.Unable to create requested service [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment]。 测试过同一段代码在eclipse下用hibernate和dbutils都可以连接到数据库,但发布到tomcat只有dbutils才能访问到数据库。 我的用是apache-tomcat-7.0.52和驱动包mysql-connector-java-5.1.7-bin.jar。 昨天才刚学了hibernate,今天遇到这问题查了一天都没发现问题. 下面是hibernate和c3p0的配置文件 ![图片说明](https://img-ask.csdn.net/upload/201710/19/1508382636_936962.png) ![图片说明](https://img-ask.csdn.net/upload/201710/19/1508382675_857886.png)
阿里云下 Tomcat 应用无法连接数Mysql据库
**1、程序没问题,在本机上调试无误,struts2 spting hibernate 2、在阿里云服务器上 配置了 JDK 1.7 + tomcat7 + mysql5.1 , OS:ubuntu64 3、将应用部署后,JSP 页面访问正常,只要涉及到连接数据库就会有如下提示** org.hibernate.exception.GenericJDBCException: Cannot open connection org.hibernate.exception.SQLStateConverter.handledNonSpecificException(SQLStateConverter.java:126) org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:114) org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:66) org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:52) org.hibernate.jdbc.ConnectionManager.openConnection(ConnectionManager.java:449) org.hibernate.jdbc.ConnectionManager.getConnection(ConnectionManager.java:167) org.hibernate.jdbc.JDBCContext.connection(JDBCContext.java:142) org.hibernate.transaction.JDBCTransaction.begin(JDBCTransaction.java:85) org.hibernate.impl.SessionImpl.beginTransaction(SessionImpl.java:1354) com.bfy.action.LoginAction.execute(LoginAction.java:89) sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) 。。。。。。。。。。。。 **4、怀疑XML文件读取也有问题,去掉过滤器直接访问一些ACTION,提示没有对应的result 5、应用池内文件权限 均为 777 6、mysql数据库工作正常,应用 所使用的为root用户,不是权限问题**
hibernate4 无法连接postgreSQL数据库
项目中要使用postgreSQL,之前用的mysql是可以连接的,但是切换到postgreSQL后,tomcat加载时就直接在: 2014-08-26 20:26:52 [localhost-startStop-1] DEBUG org.hibernate.engine.jdbc.internal.JdbcServicesImpl - Database -> name : PostgreSQL version : 9.3.1.3 major : 9 minor : 3 2014-08-26 20:26:52 [localhost-startStop-1] DEBUG org.hibernate.engine.jdbc.internal.JdbcServicesImpl - Driver -> name : PostgreSQL Native Driver version : PostgreSQL 9.3 JDBC4.1 (build 1102) major : 9 minor : 3 2014-08-26 20:26:52 [localhost-startStop-1] DEBUG org.hibernate.engine.jdbc.internal.JdbcServicesImpl - JDBC version : 4.0 这儿等待,也不报错,就是不往下执行。如果切换为mysql又可以正常启动,而且可以用mybatis连接postgreSQL数据,数据源配置都一样。 配置文件: <!-- 数据源datasource --> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"> <property name="driverClassName" value="org.postgresql.Driver"> </property> <property name="url" value="url"> </property> <property name="username" value="tapi"></property> <property name="password" value="123456"></property> </bean> <!--创建Spring的SessionFactory工厂 --> <!--和hibernate4整合没有提供专门的针对Annotation的类,直接在LocalSessionFactoryBean中已经集成--> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <!-- 注入数据源 --> <property name="dataSource" ref="dataSource" /> <!-- 设置Spring去哪个包中查找相应的实体类 --> <property name="packagesToScan"> <list> <value>com.travelsky.tapiweb.eterm.model</value> </list> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</prop> <prop key="hibernate.hbm2ddl.auto">update</prop> <prop key="hibernate.connection.autocommit">true</prop> <prop key="hibernate.current_session_context_class">org.springframework.orm.hibernate4.SpringSessionContext</prop> <prop key="hibernate.show_sql">false</prop> <prop key="hibernate.format_sql">false</prop> </props> </property> </bean> 如果改成这样,其他地方不变动: <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver"> </property> <property name="url" value="url"> </property> <property name="username" value="tapi"></property> <property name="password" value="123456"></property> </bean> 又可以连接并且正常启动,hibernate版本为4.2.0final,postgreSQL驱动jdbc4和jdbc4.1都不能成功,jkd版本是1.6,求大神解决下啊,纠结一天了
SSH连接数据库时,无法自动创建表,且tomcat无法启动
jdbc配置: driverClass=com.mysql.jdbc.Driver url=jdbc:mysql://localhost:3306/mydata user=root password=root 当数据库中没有mydata表时,无法自动创建,且tomcat启动不了,停留在Initializing Spring root WebApplicationContext。如果手动创建mydata表,tomcat可以启动,项目也能运行。 hibernate配置: <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <!-- 数据库言 --> <property name="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</property> <!-- 加载二级缓存插件(可选) --> <property name="hibernate.cache.region.factory_class">org.hibernate.cache.EhCacheRegionFactory</property> <property name="hibernate.cache.use_query_cache">true</property> <!-- 配置自动生成DDL语句 --> <property name="hibernate.hbm2ddl.auto">update</property> <!-- 在控制台打印出当前的sql语句 --> <property name="hibernate.show_sql">true</property> <!-- 注册对象关系映射 --> </session-factory> </hibernate-configuration>

单数据库系统(MySQL)升级为Master-Slave模式(Master写,Slave读)
我想将单数据库系统(MySQL)升级为Master-Slave模式(Master写,Slave读). 做了三个简单测试,如下: 1. replicationdriver+直接创建jdbc连接, 可以实现写master,读slave的目标。 2. tomcat自带的dbcp连接池+replicationdriver,可以实现写master,读slave的目标。 3. hibernate+tomcat自带的dbcp连接池+replicationdriver, 读写始终在master中进行。 不知道有没有人结合hibernate,dbcp连接池,replicationdriver在实际项目中应用过,或做过测试? 请指点! 或者有其它方式能实现此目标。 Notes: 1. 我使用的是hibernate3.0.x 2. 不准备使用MySQL Proxy 怀疑Hibernate不支持ReplicationConnection, 一个Session对应一个Connection, 不能对应一个ReplicationConnection。
用struts1.2+tomcat5.5+mysql5.1+c3p0连接池开发 出现死机现象
用struts1.2+tomcat5.5+mysql5.1+c3p0连接池开发 出现死机现象 各位朋友,向大家请教一下,我们用struts1.2+tomcat5.5+mysql5.1+c3p0连接池开发一个web应用网站。 现在我们遇到的问题是:现有已经开发的几个模块,部署到linux服务器上,服务器使用的tomcat5.5,运行一段时间就会出现死机的现象,不能登陆及查询(即:数据库操作无响应),刚开始我们初步判断是连接池的原因(因为我们连接池用的单例模式,之前由于考虑不全,出现了两个连接池对象),但是后面我们已经修改了连接池,只有一个连接池对象,再发布测试还是出现这个现象。我们还是不能确定问题出现在哪里, 只是怀疑连接池的问题,我们又做了修改(将c3p0 连接池修改为struts1.2的数据源配置),再次发布到服务器上测试,还是出现相同的问题。 现在我们能推断的问题原因有以下几种情况: 1.连接池问题 (不能确定,应为我们修改了两次连接池,还是出现相同的问题) 2.tomcat 死掉 (不能确定,网上查找了资料,已经修改了tomcat启动参数 设置jvm 的虚拟内存: set JAVA_OPTS=-Xms512m -Xmx512m) 3.mysql 数据库死掉 (不能确定,如果是数据库服务器死掉,但是通过mysql的客户端可以正常操作查询等一些操作) [b]问题补充:[/b] 补充1:Connection,statement都是在应该关闭的地方关闭了的 补充2:没有使用hibernate 补充3:编译没有报错 [b]问题补充:[/b] 补充:程序能够运行一段时间,大概20分钟左右,然后才数据库操作无响应 [b]问题补充:[/b] 我们程序里有两个线程、每隔15分钟扫描一次数据库中表,同时还有用户不停的访问!!麻烦你能否给一个连接池的配置信息!谢谢!!
hibernate 进行单元测试 没问题 在tomcat上不行
最近学习到hibernate 用的是hibernate-release-5.0.7.Final 和mysql数据库 在写junit测试的时候 不管是往数据库中添加还是删除都没问题,可是写了一个web项目用的同样的的配置文件同样的工具类 就是不行 一到config.buildSessionFactory()这句话就执行不下去了也没有异常信息 到底是为什么啊?![![图片说明](https://img-ask.csdn.net/upload/201611/05/1478275250_540393.png)图片说明](https://img-ask.csdn.net/upload/201611/05/1478275231_902040.png)

请问安卓商城的服务端如何部署(使用的structs2+hibernate框架)
最近从网上下载了一个android应用的源码,源码有2个工程,客户端和服务端,服务端是用struts2+hibernate框架搭建的。想自己运行一下试试,在android模拟器里应用可以成功加载上但打开只有只有一个layout的框架,没有内容,应该是没有连接到服务端读不出数据库内容所致。在客户端里改了connectWeb类里的请求url,在服务端里我在myeclipse添加了tomcat6.0,然后改了hibernate.cfg.xml连接数据库的参数,运行的时候直接start了 tomcat,然后我在浏览器里输入本地地址可以看到服务端的欢迎页面,然后试了一下客户端的一个请求url结果出现了500错误,调试了一下是sessionfactory为空值的原因,就是说hibernate没有连接上mysql,请问是代码的原因还是部署上有什么错误?在启动tomcat的时候需不需要设置什么参数?谢谢了

《Neural Networks and Deep Learning》读书笔记第四篇本章其实和前面章节的关联性不大,所以大可将本章作为小短文来阅读,当然基本的深度学习基础还是要有的。主要介绍了神经⽹络拥有的⼀种普遍性,比如说不管目标函数是怎样的,神经网络总是能够对任何可能的输入,其值(或者说近似值)是网络的输出,哪怕是多输入和多输出也是如此,我们大可直接得出一个结论:不论我们想要计算什么样的函数,...
聊聊C语言和指针的本质
坐着绿皮车上海到杭州,24块钱,很宽敞,在火车上非正式地聊几句。 很多编程语言都以 “没有指针” 作为自己的优势来宣传,然而,对于C语言,指针却是与生俱来的。 那么,什么是指针,为什么大家都想避开指针。 很简单, 指针就是地址,当一个地址作为一个变量存在时,它就被叫做指针,该变量的类型,自然就是指针类型。 指针的作用就是,给出一个指针,取出该指针指向地址处的值。为了理解本质,我们从计算机模型说起...
为什么你学不过动态规划?告别动态规划,谈谈我的经验
动态规划难吗?说实话,我觉得很难,特别是对于初学者来说,我当时入门动态规划的时候,是看 0-1 背包问题,当时真的是一脸懵逼。后来,我遇到动态规划的题,看的懂答案,但就是自己不会做,不知道怎么下手。就像做递归的题,看的懂答案,但下不了手,关于递归的,我之前也写过一篇套路的文章,如果对递归不大懂的,强烈建议看一看:为什么你学不会递归,告别递归,谈谈我的经验 对于动态规划,春招秋招时好多题都会用到动态...
程序员一般通过什么途径接私活?
二哥,你好,我想知道一般程序猿都如何接私活,我也想接,能告诉我一些方法吗? 上面是一个读者“烦不烦”问我的一个问题。其实不止是“烦不烦”,还有很多读者问过我类似这样的问题。 我接的私活不算多,挣到的钱也没有多少,加起来不到 20W。说实话,这个数目说出来我是有点心虚的,毕竟太少了,大家轻喷。但我想,恰好配得上“一般程序员”这个称号啊。毕竟苍蝇再小也是肉,我也算是有经验的人了。 唾弃接私活、做外...

互联网公司的裁员,能玩出多少种花样?
裁员,也是一门学问,可谓博大精深!以下,是互联网公司的裁员的多种方法:-正文开始-135岁+不予续签的理由:千禧一代网感更强。95后不予通过试用期的理由:已婚已育员工更有责任心。2通知接下来要过苦日子,让一部分不肯同甘共苦的员工自己走人,以“兄弟”和“非兄弟”来区别员工。3强制996。员工如果平衡不了工作和家庭,可在离婚或离职里二选一。4不布置任何工作,但下班前必须提交千字工作日报。5不给活干+...

活到老,学到老,程序员也该如此
全文共2763字,预计学习时长8分钟 图片来源:Pixabay 此前,“网传阿里巴巴要求尽快实现P8全员35周岁以内”的消息闹得沸沸扬扬。虽然很快被阿里辟谣,但苍蝇不叮无缝的蛋,无蜜不招彩蝶蜂。消息从何而来?真相究竟怎样?我们无从而知。我们只知道一个事实:不知从何时开始,程序猿也被划在了“吃青春饭”行业之列。 饱受“996ICU”摧残后,好不容易“头秃了变强了”,即将步入为“高...
Vue快速实现通用表单验证
本文开篇第一句话,想引用鲁迅先生《祝福》里的一句话,那便是:“我真傻,真的,我单单知道后端整天都是CRUD,我没想到前端整天都是Form表单”。这句话要从哪里说起呢?大概要从最近半个月的“全栈工程师”说起。项目上需要做一个城市配载的功能,顾名思义,就是通过框选和拖拽的方式在地图上完成配载。博主选择了前后端分离的方式,在这个过程中发现:首先,只要有依赖jQuery的组件,譬如Kendoui,即使使用...

面试官:关于Java性能优化,你有什么技巧
通过使用一些辅助性工具来找到程序中的瓶颈,然后就可以对瓶颈部分的代码进行优化。 一般有两种方案:即优化代码或更改设计方法。我们一般会选择后者,因为不去调用以下代码要比调用一些优化的代码更能提高程序的性能。而一个设计良好的程序能够精简代码,从而提高性能。 下面将提供一些在JAVA程序的设计和编码中,为了能够提高JAVA程序的性能,而经常采用的一些方法和技巧。 1.对象的生成和大小的调整。 J...
